摘要:
采用第一性原理计算研究了超硬材料BeCN2的光学性质及Ce掺杂引起它的光学性质变化.结果表明:BeCN2在可见光区域无明显吸收,折射率稳定在2.0左右,掺杂Ce后在可见光和紫外光区都有较强吸收,但反射较弱.二者可分别用作透明器件或紫外线防护等不同领域的光学材料.通过电子结构特征分析说明了Ce掺杂引起光学性质变化的机理.
Abstract:
The optical properties of ultra-hard materials BeCN2and its change resulted by the doped Ce have been investigated with the first principles method.The calculational results show that BeCN2has no absorption but has an almost stable refractive index in the visible-light range.The BeCN2doped with Ce shows strong absorption but weak reflection in all the visible and ultraviolet light range,implicating that they could be used as materials of transparent device or protection against ultraviolet light,respectively.Moreover,the mechanism of the change of the optical properties resulted from the doped Ce is explored by the electronic properties.
